Designs of stairways are highly code-regulated for life-safety reasons. Today, for
improved environmental sustainability as well as better personal health, popular
advice says to use the stairs instead of an elevator whenever practical. However
enclosed stair towers often suffer from poor temperature control and “stuffiness,” are
uninviting in appearance, or are inconveniently located. For new buildings there is
opportunity to make stairways attractive choices for occupants to use regularly. This
article discusses a study1 concerning thermal comfort and indoor air quality (IAQ) in
enclosed stair towers and looks at the effect of placement of HVAC terminal units to
test a popular design rule-of-thumb.
